Title: Thermographic copying machine
Inventor: MOCHIZUKI HIDEHIRO
IPC: G03B27/02
Filed: 1983-05-31
Abstract: PURPOSE:To prevent an accident due to temperature rises of some part of a main body, original, etc., securely and perform high-precision control by turning off a lamp when a light source or driving system for original movement stops or operates at a low speed. CONSTITUTION:Two capacitors C1 and C2 coupling with two microswitches MS1 and MS2 are charged and discharged repeatedly and alternately at a specific period through the switching of the corresponding MS1 and MS2. Their discharging currents energize a magnet relay Ry to make the relay contact, and the lamp load R1 turns on. While the light source or platen keeps on moving normally, the period of charge and discharge and the capacity are set to proper values, and the energizing current of the Ry flows from the C1 and C2 alternately, so that the lamp R1 stays on. If a fault occurs, the charge and discharge cycle of the C1 and C2 stops and the relay energizing current is therefore ceased to turn off the R1 automatically. The R1 is turned on and off intermittently and repeatedly when the moving speed is slow.

Title: Processor by classification, and program recording medium
Inventor: YAGI SHIGERU
IPC: G06Q10/10
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the unexpected rotation caused by the malfunction, by permitting the driving of a classification storing part when both of the first and second switches are operated, and rotating the classification storing part in a direction directed by the switch, on the basis of the result of the discrimination that which switch is operated first. SOLUTION: The rotation of a classification box is permitted under a condition that the both of a left switch 20 and a right switch 21 are operated. Whereby the insertion of a hand into the classification box can be prevented, because the switching operation is performed by the both hands during a time when the classification box is rotated and driven by the switching operation when a slip is taken out, or the wrong rotation and driving of the classification box can be prevented because the operation is performed by the both hands. Further a rotating direction of the classification box can be controlled on the basis of that which one of the left switch 20 and the right switch 21 is operated first. The operating condition of the left switch 20 and the right switch 21 is monitored by a program control, to control the rotation of the classification box.

Filed: 1985-05-09
Abstract: PURPOSE:To improve the reception sensitivity by detecting a signal current leaked from a receiving end to the outside of the section by means of a CT or a coupler at the receiving side so as to utilize it as a reception signal. CONSTITUTION:A sum current at each biphase obtained from CTs 61b, 61n, 62b, 62n and auxiliary CTs 63, 64 is transformed properly and given to receivers 41, 42 to compensate the current component leaded to the side of a pole transformer 1. Then proper level conversion is applied by level converters 43, 44 to correct the input to the receivers 41, 42. As to the signal current component shunted or leaked to the pole transformer 1, it is all detected and fed as a signal correcting the input to the receivers 41, 42 at the receiving side, then the reduction in the reception current due to the said leaked component cannot exist. Thus, the signal transmission rate is improved and sure reception is attained.

Title: Delay detection circuit
Inventor: KOMOTA NORIO
IPC: H04B7/08
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To obtain the delay detection circuit in which deterioration in a bit error rate characteristic is prevented by eliminating delay differences among IF signals of a plurality of systems so as to eliminate a discontinuous part of a reception signal when an antenna system receiving the signal is switched and to select an IF signal with highest reliability. SOLUTION: Two systems of IF signals IF1, IF2 are respectively given to 1-system and 2-system phase comparators 1, 2, in which the signals are respectively converted into phase information and the information is sampled synchronously with a clock signal whose period is a multiple of four of a symbol rate by 1-system and 2-system re-timing sections 3, 4. The two phase information sets to be sampled are given to a 1-system or 2-system delay detector 5 or 6, in which the phase information with a smaller delay is delayed so as to eliminate the delay difference between the two sets of the information and the information sets are converted into two delayed detection information sets, and a selector section 7 selects the information which has higher reliability.  Thus, a discontinuous part of the reception signal caused when the antenna system to receive a signal is switched is eliminated and the delay detection circuit is realized, in which deterioration in a bit error rate characteristic is prevented.
